function
Type 3DR pressure control valves are pilot-operated three-way pressure reducing valves with relief function for secondary circuits. They are used to reduce system pressure.
Pressure relief valve is mainly composed of a main valve with a control spool and a pilot control valve with a pressure regulating element.
In the starting position, the valve is open. Hydraulic oil can flow from passage P to passage A without any restriction. The pressure in passage A is applied through the bore to the area of the spool opposite the compression spring. At the same time, pressure is applied to the spring-loaded side of the control spool through the orifice and to the ball of the pilot control valve through the passage.
Depending on the setting of the compression spring, hydraulic pressure builds up upstream of the ball and in the conduit and holds the control spool in the open position. Hydraulic oil flows from passage P through the control spool to passage A until the pressure in passage A increases above the pressure set by the compression spring and lifts the ball. Control spool movement to closed position. When the pressure in passage A reaches equilibrium with the pressure value set by the compression spring, the desired pressure reduction is achieved. When an external force acting on the actuator causes a further increase in pressure in passage A, the control spool is further compressed compressing the compression spring. This opens the connection between passage T and passage A through the control port on the control spool. The amount of hydraulic oil drained to the tank ensures that the pressure does not increase. Pilot oil always leaks from the spring chamber through the pilot line to port Y. Always keep pilot oil returning to the tank at zero pressure. The reduced pressure in passage A can be checked using the pressure gauge port.

function
The DBEM valve is a pilot operated relief valve with integrated electronics (OBE). These valves are used to limit the working pressure of hydraulic systems. Depending on the electrical control value, these valves can be used for stepless setting of the system pressure to be limited. The basic components of these valves include a housing with a main spool, a superposition valve with a large pressure limit, and a proportional pilot control valve. The proportional electromagnet is also equipped with a housing with control electronics. Apply the supply voltage and control value voltage to the connector. The pressure characteristic curve of the control value is adjusted to very low manufacturing tolerances at the factory.
Model DBEME...
Pressure applied in passage P acts on the main spool. At the same time, pressure at port P is applied to the spring-loaded side of the main spool through the control circuit with nozzle. Pressure is also applied to the frame of the proportional pilot control valve through the connecting bore. The hydraulic pressure at the pilot seat overcomes the proportional solenoid control value-dependent force. If the hydraulic pressure exceeds the coil magnetic force, the pilot seat opens. Pilot oil can now flow through the control circuit to port Y and to the tank; therefore, a pressure drop occurs at the main spool on the control circuit. Release the connection from port P to T. The main spool controls the set operating pressure at port P.
Spring-loaded relief valves are integrated since hydraulic protection prevents abnormally high pressure values. This high pressure limit is a preset value based on the relevant pressure level. Within the valve operating range, the spring holds the valve holder to the valve seat and the valve core closes thereby.
If the pressure at the main spool spring chamber exceeds the valve's maximum allowable set point pressure, the carrier will press against the compression spring and the connection to the spring chamber will open. Pilot oil flows into the tank through port Y. Due to the presence of the control circuit, a pressure drop occurs at the main spool. Release the connection from port P to T. The main spool controls the large operating pressure set at port P. If necessary, the preset pressure can also be reduced by means of an adjusting element. Port Y must be connected from the outer tube to the tank. The tank must be connected after pressure relief. The valve can be unloaded or high pressure limited through port X.

To set the system pressure, control the value at the control electronics. The electronics drive the solenoid with current according to the control value. The proportional electromagnet converts the current into mechanical force, which acts on the valve frame through the armature plunger. Push the valve holder into the valve seat and block the connection between port P and T or Y. If the hydraulic pressure on the carrier is equal to the coil magnetic force, the valve controls the set pressure by lifting the carrier off its seat, allowing hydraulic oil to flow from port P to T or Y. If the control value is zero, the control electronics apply only a small control current to the proportional electromagnet and a small constant pressure is also set.

DRE(M) valve is a pilot operated pressure reducing valve. These valves can be used to reduce operating pressure.
The basic components of these valves are a pilot control valve with proportional solenoid, a main valve with main spool, and an optional check valve.
Model DRE...
The pressure in channel A can be set according to the control value by means of proportional electromagnets.
The spring holds the main spool in its initial position at rest, i.e., when there is no pressure in passage B. The connection from channel B to channel A is closed. Therefore, start-up jumps can be avoided.
Pressure applied in passage A acts on the face of the main spool through the bore. Pilot oil flows from passage B through the orifice to constant current control, which keeps pilot flow constant regardless of the pressure drop between passages A and B. pilot flow
The constant current control flows into the spring chamber, through the holes and, through the valve seat, into passage Y and back from there. Preset the desired pressure in channel A via the associated amplifier. The proportional solenoid moves the valve carrier toward the seat and limits the pressure in the spring chamber to the set value. If the pressure in passage A is below the preset control value, the higher pressure in the spring chamber will shift the main spool to the right. The connection from B to A is open. If the setpoint pressure at A has been reached, the forces at the main spool are balanced-the main spool is in the control position.
Pressure at spool end of channel A = spring force at spool end of spring chamber–
If the pressure at A (e.g.) is to be reduced in a vertical hydraulic cylinder (e.g. cylinder piston in cut-off position), a lower control value can be preset via the control electronics, so that the lower pressure value is preselected and immediately appears in the spring chamber. The higher pressure value acting on the main spool surface at A pushes the main spool toward the protection plug to the OFF position. The connection A to B is blocked and the connection A to Y is open. The force at the spring is now opposed to the hydraulic force acting on the main spool surface. At this main spool position, hydraulic oil can flow from passage A through the control edge to Y into return.
When the pressure at A drops to the sum of the pressure in the spring chamber and p of the spring, the main spool closes the large control orifice in the socket at control edge A to Y.
The residual pressure difference with respect to the new control value at A is approx. 10 bar and the current pressure can only be relieved via the control orifice. This results in a good transient response without pressure undershoot. In order to achieve free backflow from channel A to channel B, a check valve can be optionally installed. Part of the charge flow at passage A can also flow back through the open main spool A to Y control edge.
Model DREM...
In order to provide hydraulic protection against excessive pressure at port A due to impermissible high electrical control currents on the proportional solenoid, a spring-loaded relief valve may optionally be installed to limit high pressures. This high pressure limit is preset based on the relevant pressure level.

(Z) Type DBE pilot-operated proportional relief valve is activated by proportional solenoid. This valve can be used to limit system pressure. Depending on the electrical control value, these valves can be used for stepless setting of the system pressure to be limited. The basic components of these valves are the pilot control stage and the main stage. The pilot control assembly consists of a proportional solenoid, a frame, and a seat. The main stage consists of a housing and main spool assembly. Proportional electromagnets convert electrical current proportionally into mechanical force. An increase in current results in a corresponding increase in coil magnetism. The system pressure can be set according to the control value via proportional electromagnets. The pressure applied by the system to passage P acts on the right side of the main spool assembly. At the same time, system pressure will act on the spring-loaded side of the spool through the control circuit equipped with the nozzle. Through the seat of the pilot line, the pressure at the spring chamber frame overcomes the force of the proportional solenoid. When the pressure reaches a preset value, the valve frame is lifted from the seat. Pilot oil (depending on the model) can now drain either to the outside through port A (Y) or to the internal tank, which also limits the pressure on the spring-loaded side of the main spool. If system pressure continues to ramp up, high pressure on the right side of the spool will push the spool to the left to the P to T control position. At small control currents (corresponding to zero control values), the small setpoint pressure will be set.
Watch out!
Prevent empty tank line operation. A preload valve (preload pressure approx. 1 bar) must be installed under the appropriate installation conditions.

The directional valve for WE models is a solenoid operated directional spool valve that can be used as a solenoid assembly. They are used to control the start, stop and direction of flow.
The directional valve basically consists of a housing, one or two electromagnets, a control spool and a return spring.
In the de-energized state, the control spool is held in the neutral or initial position by the return spring (except version O).
When the electromagnet in the hydraulic oil is switched on, the control spool is moved from its rest position to the desired end position. This signals the desired flow direction based on the selected symbol.
When the solenoid is switched off, the control spool is pushed back to the neutral or initial position (except valves with OF and valves without spring type O
Auxiliary operation allows manual switching of the valve without energizing the magnet.
The hydraulic system must be properly vented to ensure proper operation.
Without spring return" O" (symbols A, C and D only)
This model is a directional valve with two switching positions and two electromagnets without actuator. Valves without spring return at the control spool have no defined initial position in the de-energized state.
Without spring return, with device" OF" (symbols A, C and D only)
This model is a directional valve with two switch positions and two electromagnets with actuators. The control valve core is fixed in the corresponding switching position through the device. Therefore, no current needs to be applied to the electromagnet during operation, which contributes to energy-saving operation.
Model 73... A12" (soft handoff behavior)
The combination of control spool and solenoid reduces the number of reversing strokes that occur when the valve opens or closes. The reversing stroke (measured as acceleration value a) can be reduced by approximately 85% compared to standard valves, depending on the type of control spool (see acceleration value).
Note:
Pressure spikes in drain lines connecting two or more valves may cause unintended control spool movement on models with actuators. It is recommended to lay a separate return line or install a check valve in the drain line.
Due to the design principle, internal leakage occurs in the valve, and the leakage volume increases during the service life.
throttle insert
Depending on the prevailing operating conditions, throttle inserts will be required if flow exceeding the performance limits of the valve is likely to occur during switching.

The directional valve for WE models is a solenoid operated directional spool valve. These valves control the start, stop and direction of the fluid.
These directional valves consist essentially of a housing, one or two coils, a control spool and one or two return springs. In case of power failure, the control spool is fixed in the center position or initial position by the return spring. The control spool is actuated by a coil with wet pins.
To ensure proper operation, make sure that the pressure chamber of the coil is filled with hydraulic oil!
The force of the coil acts on the control spool via the push rod and pushes the latter from its rest position to the desired end position. This frees up the desired flow direction depending on the symbol. After the coil is demagnetized, the return spring pushes the control spool back to its rest position.
Manual emergency operation controls the spool when the coil is not energized.

The directional valve for WE models is a solenoid operated directional spool valve that can be used as a solenoid assembly. The valve controls the start, stop and direction of the fluid.
The directional valve basically consists of a housing, one or two electromagnets, a control spool and a return spring. In the de-energized state, the control spool is held in the neutral or initial position by the return spring (except version O). When the electromagnet in the hydraulic oil is switched on, the control spool is moved from its rest position to the desired end position. This signals the desired flow direction based on the selected symbol.
When the solenoid is switched off, the control spool is pushed back to the neutral or initial position (except valves with OF and valves without spring type O
Auxiliary operation allows manual switching of the valve without energizing the magnet.
The hydraulic system must be properly ventilated to ensure proper functioning.
Without spring return" O" (only applicable to symbols A, C and D)
This model is a directional valve with two switching positions and two electromagnets without actuator. Valves without spring return at the control spool have no defined initial position in the de-energized state.
Without spring return, with device" OF" (symbols A, C and D only)
This model is a directional valve with two switch positions and two electromagnets with actuators. The control valve core is fixed in the corresponding switching position through the device. Therefore, no current needs to be applied to the electromagnet during operation, which contributes to energy-saving operation.
Model 73... A12" (soft handoff behavior)
The combination of control spool and solenoid reduces the number of reversing strokes that occur when the valve opens or closes.
The reversing stroke (measured as acceleration value a) can be reduced by approximately 85% compared to standard valves, depending on the type of control spool (see acceleration value).
Note:
Pressure spikes in drain lines connecting two or more valves may cause unintended control spool movement on models with actuators. It is recommended to lay a separate return line or install a check valve in the drain line.
Due to the design principle, internal leakage occurs in the valve, and the leakage volume increases during the service life.
throttle insert
Depending on the prevailing operating conditions, throttle inserts will be required if flow exceeding the performance limits of the valve is likely to occur during switching.

Z4WE directional valve is solenoid operated directional spool valve. The valve controls the start, stop and direction of the fluid.
The directional valve basically consists of a housing, one or two coils, a control spool and two return springs.
In the non-operating state, the control spool is held in the center position or initial position by a return spring. Control spool is operated by wet pin coil.
The hydraulic system must be properly ventilated to ensure proper functioning.
The force of the coil acts on the control spool via the plunger and pushes it from the rest position to the desired end position. This releases the required flows A② to A① and B② to B①.
After the coil is de-energized, the control spool is pushed back to the rest position by the return spring.
Optional manual emergency operation moves the control spool without energizing the coil.
Note:
Due to the design principle, the valve will inevitably have internal leakage, and the leakage will increase with the increase of service time.
Permissible shock and vibration loads are described in parameter sheet 08012.
Note:
The solenoid valve generates voltage spikes during closing. In order to prevent electromagnetic interference in the system and damage to the valve control, interference protection circuits must be provided on the system side. Alternatively, connectors with integrated interference protection circuits can be selected.
Note:
When establishing electrical connections, the protective earth conductor (PE ) must be connected correctly.
It must be routed in a way that reduces tension!
Cable bundle coils are only suitable for installed cables.
During operation, the connector shall be locked. During normal operation with loads, it must not be plugged in or disconnected.
Protective earth conductor cross section equal to or greater than line cross section of power supply.
The valve mounting face must be connected to the protective earth conductor system.
